What the hell is wrong with Joss Whedon?
I suppose I should have expected the turn of events in Act III of Doctor Horrible's Sing-Along Blog, given his past track record, but damn, that guy must really hate his audience.
Update: Karen has found a quote indicating that he thinks it's proof that he's a good writer when people complain about him doing it. I guess he must really need validation, since he does it in every single series.
